2 1. Users are reporting long response time delays in transactions that previously would run with sunscald response. The system administrator knows these transactions are RPG IV-SQL based programs. Which of the following would be the first set in determining the problems. A. Use Management Central to start a job monitor for system and select the SQL submonitor display. B. Use iseries Navigator, SQL Performance Monitor to conllect and analyze the SQL performance of the jobs. C. Start debug on one of the on-line jobs and use Performance Explorer to analyze the jobs database access plan. D. Use iseries Navigator to create a database map of the tables used in the transactions and watch for high I/O rates. 2. Using the example below, what is the cumulative PTF level of the system?

A system administrator needs to add 100 users to a V6R2 system without impacting response times, Which of the following would be the first step in determining the current performance of the system? A. Define a performance collection agent in idoctor for iseries. B. Define a performance collection object within iseries navigator. C. Use Performance Explorer to collect generalized performance data. D. Use the Workload Estimator to show existing performance constraints. 9. Which of the following can have an impact on determining the interactive workload requirements of an iseries? A. Active subsystems. B. Active controllers. C. Active user profiles. D. Active display sessions. Answer: D 10. A Manufacturing company has three remote sites and a total of six distributed AS/400 systems. The

5 company would like to accomplish the followings. A. Centralize to a single system. B. Maintain each system workload and identity attributes. C.

Implement High Availability and replicate each system to a single system. B. Implement LPAR on a centrally located system and consolidate the individual systems onto multiple partitions. C. Transfer all systems to the central location and create an iseries cluster to form a single "logical" system. D. Consolidate all the systems into a single partition on a syst3em with a CPW rating that matches or exceeds the accumulated CPW of the individual systems. 12. Which of the following disk drive considerations has the greatest impact on system performance? A. Number of disk drives on a bus. B. User versus available disk space. C.

QMAXACTLVL system value. 15. An iseries Administrator would like to monitor the performance of all four of the machines in the data center at one time. If a certain level of interactive CPU is reached, the administrator wants to receive an . What needs to be done to satisfy the requirements. A. In Management Central, set up a system group monitor job with a threshold action. B. In iseries Navigator create endpoints for each of the systems and set up a threshold job monitor. C. Add an exit program to the WRKACTJOB command to intercept the CPU statistics and process the . D. Start PM/400 and use the PM/400 notification options to send the when the threshold is reached. 16. Which of the following will enable an administrator to establish an ongoing analysis of the performance and utilization of an iseries. A. Upload the performance data to the IBM workload Estimator. B. Activate Performance Manage/400 to automatically upload data to IBM. C. Enable PPP communications between the iseries and the IBM Benchmark Center. D. Utilize the no-charge OS/400 performance analysis tools to print monthly reports. 17. On a system that does not have Performance Tools for iseries (5722-PTI), how can performance data be collected for analysis on a different system that has Performance Tools installed. A. Use Electronic Service Agent for iseries.
